unable to open device monitor on Passport

using the official 10.3.0.908 or build version 10.3.0.1418, having some weird battery drain issues used to last 2 days now getting max 1 out of it. Main problem is i cant open device monitor to see whats eating my battery not sure if anyone has come across this but would be pretty helpful as i wanna reduce my battery kill.

restarted my device with no avail also did a hard reset hoping for a few other ideas, device monitor just sits there and refuses to load any info no matter how long i leave it had it going for 10 mins when it used to load in 10 secs.

You haven't loaded anything "new" in the last couple of days? Usually, there is an event that is the genisis.
And my first thing I would look at is BBM. A number of folks have started to see this start to eat batteries.
Any BBM chats running? Shut down any chats/messages you have, and try the hard reset again after that.

funny part is i have been having trouble opening device monitor over the last 2 weeks but shrugged it off but i kinda need it now, the only thing i have done new in the last week is load cobalts google play store hack other than that nothing has changed.

well after another hard reset i can get into it for now, but the usage doesn't make sense off charger 6:15 am to now at 1:45 pm the main usage is display at 16 system at 8 and standby at 4% everything else is under 1%. battery currently sits at 60%
